A 20m Fink Truss are spaced at 'S' meters o.c. the purlins are made up of C10X20 sections and are spaced 1.1967m on centers. The truss has a height of 4m. Roof LL is 'RLL' N/m2 of roof surface and roof covering is assumed to be 'RDL' N/m2 of roof surface. Determine whether the purlins are adequate to carry such loadings. Given: Fy=248 MPa w=29.76 Kg/m A=3787.09 mm^2 Ix=32.84×10^6 mm^4 Iy=1.17×10^6 mm4 Zx=317.91×10^3 mm3
Note: Hi, pls need help. Any solutions are highly appreciated. I will rate this right away. Thank you in advance!
Considering sag rods and tie rods at midspan, what is the maximum moment about minor axis in N-m? (2 decimal places)
